ANALYSIS OF OZONE AND WATER VAPOR FIELD MEASUREMENT DATA

In this report the field measurements of atmospheric ozone and water vapor in the stratosphere are critically reviewed, using information available as of summer 1978. Our data sources are the results of field measurements published in the journal literature. Preliminary data have been excluded. We also eliminated some of the older data after a critical analysis had shown that their accuracy is very low or that an unreliable technique had been used. The available data have been analyzed to derive periodic and aperiodic variations, such as natural variability, diurnal and seasonal variations, and long-term trends. Latitudinal variations exist, caused by transport within the stratosphere from the source regions to the sinks. The results of transport through the tropopause are evaluated and described although no independent studies have been conducted by the author. Global inventories have been derived from the vertical profiles of concentrations. No comparison has been made between field measurement data and models.
